Linus Torvalds has just released Linux 4.16: So the take from final week of the 4.16 release looks a lot like rc7, in that about half of it is networking. If it wasn’t for that, it would all be very small and calm. We had a number of fixes and cleanups elsewhere, but none of it made me go “uhhuh, better let this soak for another week”. And davem didn’t think the networking was a reason to delay the release, so I’m not. End result: 4.16 is out, and the merge window for 4.17 is open and I’ll start doing pull requests tomorrow. Outside of networking, most of the last week was various arch fixlets (powerpc, arm, x86, arm64), some driver fixes (mainly scsi and rdma) and misc other noise (documentation, vm, perf). The appended shortlog gives an overview of the details (again, this is only the small stuff in the last week, if you want the full 4.16 changelog …

Linus Torvalds released Linux Kernel 4.6 earlier today: It’s just as well I didn’t cut the rc cycle short, since the last week ended up getting a few more fixes than expected, but nothing in there feels all that odd or out of line. So 4.6 is out there at the normal schedule, and that obviously also means that I’ll start doing merge window pull requests for 4.7 starting tomorrow. Since rc7, there’s been small noise all over, with driver fixes being the bulk of it, but there is minor noise all over (perf tooling, networking, filesystems, documentation, some small arch fixes..) The appended shortlog will give you a feel for what’s been going on during the last week. The 4.6 kernel on the whole was a fairly big release – more commits than we’ve had in a while. But it all felt fairly calm despite that. Linux 4.5 added support for GCC’s Undefined Behavior Sanitizer flag (-fsanitize=undefined) which should …

Linus Torvalds announced the release of Linux Kernel 3.15 last Sunday: So I ended up doing an rc8 because I was a bit worried about some last-minute dcache fixes, but it turns out that nobody seemed to even notice those. We did have other issues during the week, though, so it was just as well. The futex fixes and cleanups may stand out, but as usual there’s various other random fixes since rc8 in there too: mainly drivers (drm, networking, sound, usb etc), networking, scheduling and perf tooling. But it’s all been fairly small and quiet, which *may* of course be due to the fact that last week was also the first week of the merge window for 3.16. That might have distracted some developers. I’m not entirely convinced I liked the overlap, but it seemed to work ok, and unless people scream really loudly (“Please don’t _ever_ do that again”) and give good reasons for doing so, I might end up doing that …

Most of the time, when you want to root an Android devices, you may think you have to start your computer, and in many cases, it has to be a PC running Windows, which can be a real pain. Google does not allow apps that provide root access in Google Play, and all you can install are apps that can check whether your device is rooted such as Root Checker. For some reasons, today I needed to root my smartphone (ThL W200, Mediatek MT6589T), and I looked for a method working with Linux, and I did not find any, but I came across Framaroot, an Android app, that allows you to do that within your Android device without external hardware required. Framaroot is very easy to use and support different exploit in order to provide root access to many devices based on Mediatek (Boromir or Faramir exploits), Qualcomm (Gandalf exploit), Samsung Exynos (mutiple exploits), as well a few devices based …

Gumstix has recently unveiled several solution kits featuring their Overo and DuoVero Computer-on-Modules (CoMs), Pepper single board computer, and several expansions boards, together with required accessories, and software packages, in order to help their customers getting started more easily. All these solutions are based on Texas Instruments OMAP3, OMAP4, and/or Sitara processors, and run Linux (Ubuntu or Yocto), and sometimes Android for the kits with displays. The solutions kits target 6 different types of applications and/or markets: Robotics Robotic Development Kit (Pictured above) with one Overo AirSTORM CoM (OMAP3703), and RoboVero expansion board. The kit is better suited for motor control applications. Mobile Robotic Development Kit with one Overo AirSTORM CoM, and Turtlecore expansion board to be used with iRobot Create. The kits ship with a Linaro (Ubuntu for Overo) system card and Robot Operating System (ROS) pre-installed. Handhelds 3.5″ Handheld Development Kit featuring Overo AirSTORM CoM with Alto35 cutomizable LCD touchscreen. 4.3″ Handheld Development Kit with Pepper SBC and …

Lernstift is a digital pen running Linux that aims at helping children learning how to write by vibrating when they’ve made calligraphy or orthography errors. I’ve covered the overall concept in an earlier post, which you can read for details. The company has made some progress, and they have just launched a kickstarter campaign where you can pledge 99 GBP (about $150) to receive the pen later this year or in early 2014. We do know a little more technical details. The first prototype was based on Gumstix Overo (TI OMAP3 or Sitara), but they are now working to design a custom board based on the platform for the final design. The pen comes with 128 MB RAM and runs embedded Linux. In order to gather handwriting data, Lernstift leverages a motion sensor that combines gyroscope with accelerometer, and adds a magnetometer. They’ve got a drawing with Freescale MMA9950L, but it’s not quite sure whether they’re using this chip or …
